When connecting the unit to your PC, make sure to follow all warnings 

and directions from your computer manufacturer.

 

»

We shall not guarantee the unit's operation if it has been connected to a 

PC using a USB hub or a USB extension cable.

 

»

Do not insert any foreign objects into any of the units' jacks.

 

»

If the unit gets dirty, wipe it with a clean cloth.

 

»

Make sure to remove dust and dirt from plugs of any cables.

 

»

Battery terminals may provide insufficient contact due to age or vibration. 

This may lead to data loss.

 

»

Please note that this document has been written based on the presup-

position that details about contracts with an Internet provider, specific 

network environments and the set-up of any other necessary equipment 

to enable network connection has already been taken care of by the User 

and that connection has been confirmed as workable. T&D Corporation 

shall not be responsible for any damages which a contractor, a user or 

a third party may suffer, whether direct or indirect, due to the inability to 

communicate or use communication devices.

 CAUTION

Notices about Sensors

 

»

Do not connect any sensor to the unit other than those specified by T&D 

Corporation.

 

»

Make sure to use sensors within the measurement range indicated in the 

specifications for that sensor.

 

»

Do not connect the sensor to any data logger other than those specified 

by T&D Corporation.

 

»

Do not expose the sensor to a strong impact. This may adversely affect 

measurement accuracy and cause damage or malfunction.

 

»

When the sensor is not to be used for a long period of time, please store it 

at normal temperature and humidity.

 

»

Do not use the sensor on the human body.

Temperature-Humidity Sensor

 

»

If extremely severe temperature changes occur, it may result in large errors 

in humidity measurement. Once the sensor's temperature becomes stable, 

the measurements will return to normal.

 

»

The temperature-humidity sensors will with normal use experience losses 

in precision and sensitivity over time due to degradation.  If the sensor is 

being used in an unsuitable environment (smoky or dusty places) it may 

be necessary to change the sensor sooner.

 

»

The included sensor is not water resistant. If the sensor gets wet, imme-

diately remove the sensor from the unit and wipe it with a clean cloth as 

soon as possible. Then allow the sensor to dry in normal room tempera-

ture before using it again.

 

»

When using the sensor in an environment where the humidity is under 

30 %RH, the measurements may sometimes fluctuate. This is not abnormal.

 

»

Do not expose to condensation, dampness, corrosive gases, or organic 

solvents.

Thermocouple Sensors

 

»

We do not handle the sale of Thermocouple sensors. Please prepare a 

commercially available sensor.

 DANGER

To Prevent Serious Accidents

Do not disassemble, repair or modify the unit and/or accessories.

Do not use the unit in any environment that is exposed to chemicals 

and harmful gases. Doing so may cause corrosion and/or other dan-

ger to the unit. Also, coming in contact with hazardous substances 

may cause bodily harm to the user or people nearby.

This product is not water resistant. If water or a foreign object enters 

the case, immediately remove batteries and stop using it.

Do not touch the unit or AC adaptor during thunder and lightning, as 

this may cause electrocution.

Do not handle the unit, remove batteries or cables with wet hands.

This product has been designed for private and/or industrial use only. 

It should not be used in situations where strict safety precautions are 

necessary such as with medical equipment, or in systems directly or 

indirectly connected with human life or well-being.

Do not drop or expose the unit to a strong impact.

Do not cut or process the cords for the communication cables. Also, 

do not twist, pull on or swing any of the cords.

To prevent damage to the unit from static electricity, remove static 

electricity from your body by touching metal around you (such as a 

door knob and window frame) before touching the unit.

Place and store the unit and accessories out of the reach of children.

We are not responsible for any damage, malfunction or trouble, 

whether direct or indirect, caused by the use of our product.

Do not use any battery, sensor, or cable other than those specified 

by T&D Corporation.

Do not put anything on top of the cable or the unit. This may cause 

overheating.

Do not disconnect the USB cable during USB communication. Doing 

so may cause adverse effects to the unit and/or PC.

Make sure that sensor and cable plugs are all inserted fully, so as not 

to cause an improper connection. Also, when unplugging the cable 

from the unit, do not pull the cord, but hold the connector to discon-

nect.
If the unit produces heat, emits smoke or a strange smell, or makes 

unusual noise, immediately remove the batteries and stop using it. 

Also, unplug the unit from the PC.
If the unit is not to be used for a long period of time, remove batter-

ies. Leaving batteries inside the unit may cause battery leakage and 

malfunction. Install new batteries when starting or re-starting to use 

a unit.
For TR-75wb / TR-75nw: Ch.1 and Ch.2 terminals are NOT electrical-

ly isolated from each other. Do not attach non-isolated thermocouple 

sensors to objects connected to a live voltage. This may cause a 

short circuit or an electrical shock.

 CAUTION

Do not place or store in the following areas:

 

»

Areas exposed to direct sunlight

 

»

Areas subject to direct flames or heaters, as well as areas in which hot air 

accumulates and creates extremely high temperatures

 

»

Areas exposed to static electricity

 

»

Areas exposed to strong magnetic fields

 

»

Areas exposed to water leakage

 

»

Areas subject to condensation or wet areas

 

»

Areas exposed to excessive vibration

 

»

Areas exposed to excessive smoke, dust or dirt.

 CAUTION

Other Precautions

 

»

Use the unit in the specified operating environment. Do not use it for any 

purpose other than for which it was designed.

 

»

Condensation may occur inside the case when a unit is moved from one 

environment to another where there is a great difference in temperature.

 

»

Do not use the unit in wet areas or places exposed to water such as bath-

room.

About TR-71wb / TR-71nw Internal Sensor

Channel 1 has an internal temperature sensor. When an external sensor is not connected, the 

internal sensor will be used.

About TR-75wb / TR-75nw Input Terminal

When connecting thermocouple wires to the input terminal, make sure that the positive and 

negative connections are in the proper order. If the polarity is incorrect, changes in temperature will 
be reversed (when the real temperature increases, the measured temperature will decrease).

Wiring Connections

Connect and disconnect the thermocouple wire from the hole while 
pressing the input terminal button with a screwdriver or other such tool.  
Do not try to pull out the wire without pressing the button.

Compatible Wires

Single wire:   0.32 to   0.65 

 (AWG 28-22)

Twisted wire: 0.08 to 0.32
